Hundreds of BBC News Online readers are dieting for the New Year. And it's not too late to join in - pick your celebrity-endorsed diet here.

On Monday, we launched a bold attempt by BBC News Online staff and readers to get into shape for the New Year.

Inspired by the numbers of celebrities who flaunt their chosen diets, we decided to join their bandwagon.

Hundreds of you have e-mailed to say you too are joining in, or to give encouragement or tips to those of us who are.

And there have been plenty of other ideas for getting healthier.

Ruth, UK, says she recommends drinking plenty of water, adding a low sugar dilute if plain water is too boring. "Not only has it made my skin better and I have more energy it fills me up and I tend to snack less," she says.

Chris, UK, made a point picked up by many of you, saying simply: "Exercise... exercise... exercise...."

9/10 adults agree healthy eating and more activity is best approach

Yet more than half of UK adults are overweight

One in four is on a diet at any one time

98% will regain weight lost - and put on more

Amanda questions the whole ethos of picking particular things to avoid. "If somebody told you could put as much petrol as you wanted into in your car but you could no longer put oil, water, antifreeze etc. into it, would you listen to them?

"Probably not, because after a while, you know that the car wouldn't run properly, as it needs more than just petrol to work," she says. "Why can't people treat their bodies with the same respect, understanding that their bodies are complex and amazing 'machines' that need the right combinations of protein, fat, dairy, fruit & veg and carbohydrates to work properly."

It's a point of view which found some sympathy with Michael, UK. "I've gone down by a stone and a half in the last year, on what I call the 'Micawber Diet', named after the character in David Copperfield. As Micawber might have said: 'Calorie income 2200 calories, calorie expenditure 2600 calories, result: happiness. Calorie income 2600 calories, calorie expenditure 2200 calories, result: misery.'

Anne Bennett adds, somewhat unhelpfully: "I've gone on the Vodka diet and have lost five days."

Here are details of the various diets, and the brave souls who are taking part.

Carol Vorderman's detox: cuts out caffeine, booze, meat and dairy products, and favours raw fruit and veg as well as lots of nuts and seeds

Glycemic Index diet, as followed by Kylie: processed foods and carbs such as white rice and potatoes are off-limits, but allows red wine and dark chocolate

Atkins diet, a la Brad 'n' Jen: a hi-protein, lo-carb regime in which fat is fine but fruit and veg are limited

Blood type diet, as followed by Martine McCutcheon: Os are "hunters" best suited to a meat-heavy diet, while As should be largely vegetarian

Food combining, a favourite of Liz Hurley: avoid eating carbs and proteins together

Carol's detox: Katie Hamilton, of CBBC Newsround, says: "After a blissful week eating meals cooked mainly with butter, cream and wine, I feel the need to punish myself with a full body detox - bring on the brown rice, I need your help Carol!"

Kylie's diet: Pete Clifton, our editor, says: "I was 12st for years, but my stomach has taken on a life of its own. After a Christmas of wall-to-wall eating and drinking, one of my children suggested I should be in the Super Sumo cartoon show. I saw a model of Kylie at Madame Tussaud's recently, and I reckon she is in better shape than me. But I've read that her job allows her to try out 'bottom enhancing moves' to complement the diet. I could be struggling on that front."

Brad 'n' Jen's regime: Cathy Grieve, of BBC Newsgathering, says: "I am overweight and so unfit - I suffer from a sweet tooth constantly. After the Christmas splurge I feel all my clothes are a little too tight and need to remedy that one fairly quickly as I don't think I can afford a new wardrobe."

Martine's diet: Peter Sharples, a systems administrator, bemoans his love handles. "I am not overweight; but there are only so may times that I can take friends and family saying 'you've put on the beef, mate'. I fear that further addition to my flabulous repertoire will lead to a stripy suntan from the creases in my tummy this summer."

Liz's regime: Ania Lichtarowicz, of our Sci-tech team, says "While I don't hold with fad diets, I'm desperate to lose half a stone and get back into an outfit for a friend's wedding."
